I adapted for usewith wind mills, for lubricating the parts thereof, andicont rolled by tion.

the movementot' the vane into and out of ,operativeposition to, supply the-lubricant. In edran g Figure 1 is a; top, plan view ,of a,,wind

the, improved lubricator; I Fig. 2 is an enlargeddetail ot agport-ion iFts- Fig. 3 is a perspectiveyiew of thelubriwi P r s in se t Fig. 4 is a perspective view of the pawl. F ig.;. 5,,is 1a iverticalisection,showing the; inner and outer sections assembled.

The present embodiment of the invention is shown in connection with the main shatt 15 of a wind mill, to which is connected at one end a fan 16 and at the other the crank 17 having the wrist pin 18 upon which is journaled the gearing of the link 19 connecting the crank to the operating mechanism of the pump. As shown, the bearing or bushing 20 in which the shaft 15 is journaled has an internally threaded opening 21 in which is engaged the lower section 1 of the lubricator, the said section having a re duced nipple threaded into the opening. An oil-way 22 extends downward from the opening 21 into the shaft 15 and then longitudinally thereof, and then radially through the crank to the wrist pin 18. The passage opens into the wrist pin and has a radial opening in the bearing of the link 19. This inner section 1 of the lubricator has a polygonal portion for engagement by a wrench or the like to turn the section into place, and an outer section 2 cooperates with the inner section, the said outer section, being in effect, a cap which screws on to the inner section.

This outer section, as shown, has a series of ratchet teeth 14:, the said ratchet teeth being of considerable width as shown, and extending from near the top to near the bot t )m;. of the section The section also has a cross head or handlalfi for convenience in turning the same, and the lubricantis placed .Wglthill. the interior of the sections .which provide a chamber for the, same. A bracket is a ra ged 9 h po yg n por n 01? the. inner, section,. and. this bracket. has an --=1 .PFY F. ex ensi 5a o whi h i conne 011 6, end of a; spiral spring 4 The coils of th sspr ngenoircle the teeth 14 of theouter section spaced relation, and the other endof the spr ng carries a, pawl 3; which cooperates with tl16,;t66tl1"l4 ()f the. outer seeholding pawl 9 is. secured to the upward extension .5? of the bracket ,5, and th s pawl s adapted for engagement with a notch-13 in the under edge, of theinner coil of the spring. The; pawl, 3 is connected by a flexible member 12 with thaturning! vane 23,01? the wind ,inil-l, the said-yanehawing a lateral arm24 ,togvhich the, cord is,connect hwanesw ssf om the-i perative dotted line position of Fig. 1 to the .loper tiv iull. iueipositionl trac ion, i l e ,anade upon the cord, and the pawl 3 will be operative to move the outer section the distance of one tooth, thus expressing a portion of the contents of the lubricator through the passage 22 to the parts to be lubricated. It will be noticed that other passages 25 in the form of grooves are provided in the shaft 15, these passages communicating with the opening of the inner section through which the lubricant passes, and the lubricant is thus supplied to the shaft 15 as well. as to the wrist pin 18.

Means is also provided for indicating when the lubricant is exhausted. The said means comprises a lever 7 which is pivoted to an extension 8 of the bracket 5 at the opposite side from the extension 5. One end of this lever carries a signal target 26, and the other is in position to be engaged by the section 2 when it is threaded down as far as it will go.

In operation, when the vane is in the dotted line position of Fig. 1 the lubricator will be inoperative. When, however, the vane is swung into the full line position of Fig. 1, the pawl 3 will be operated to move the outer section to express a portion of the lubricant, which will lubricate the parts during the running of the mill. As soon as the vane swings into inoperative position the supply of lubricant is checked. Vhenever the lubricant is exhausted the target 2-6 will be swung into position to indicate that such is the case, and that more lubricant should be supplied. the outer section may be adjusted by the length of the cable or cord 12. r

It will'be understood that the pawl will move the ratchet wheel as great a distance as may be required, whether one or two or more teeth. This will depend upon the number of ratchet teeth.

I claim:

1. In combination with the shaft and the bearing therefor, said bearin having an internally threaded opening an the shaft passages leading from the opening to the parts to be lubricated, of a lubricator comprislng an internal section having threaded engagement with the opening of the bearing, an

outer section in the form of a cap threaded onto the inner section, said cap having a series of ratchet teeth extending the full length thereof, a bracket heldby the inner section, a spiral spring carried by the bracket, the coils of the spring encircling the outer section, a pawl at the free end of the spring cooperating with the teeth, means for swinging the pawl,'and a holding pawl for the section.

2. In combination with the shaft and the bearing therefor, said bearing having an in ternally threaded opening and the shaft pets The extent of movement'of sages leadingfrom the opening to the parts to be lubricated, of'a lubricator comprising an internal section having threaded engagement wlth the openin of the bearing, an

outer section in the form of a cap threaded on to the inner section, said cap having a series of ratchet teeth extending the full length thereof, a bracket held by the inner section, a spiral spring carried by the bracket, the coils of the spring encircling the outer sectlon, a pawl at the free end of the spring cooperating with the ratchet teeth,

engagement with the opening of the bearing,

an outer section in the form of acap threaded on to the lnner sect on, means for advancing the cap to move the same. down ward, a signal, and means controlled by the c cap at the end of its downward movement for operating the signal.

4:. In combination with the shaft and the bearing therefor, of a forced feed lubricator for lubricating the shaft, means controlled by the movement of the shaft for controlling the operation of the feed.
